INCANDESCENT GAS-BURNER.

Specification of Letters Patent.

Patented Nov. 14, 1905.

Application filed December 13,1904. Serial No. 236,656.

To all whmn it may concern.-

Be it known that I, MONTFORD KAY, engineer, a subject of the King ofGreat Britain, residing at 54 London road, Clapton, in the county ofMiddlesex, England, have invented new and useful Improvements in orConnected with Incandescent Gas-Burners, of which the following is aspecification.

This invention relates to atmospheric burners in connection with whichincandescing mantles are employed, being of the inverted type. Inburners of the kind as heretofore constructed difliculties have beenexperienced in keeping the head of the burner at aproper temperature andin preventing the inductive action of the gas issuing from the nipplefrom drawing in burned gases instead of pure air.

The invention comprises means whereby the burned gases do not come intocontact with the head or mixing-chamber of the burner, the burner beingconstructed of any appropriate material, and suitable devices forsupporting the mantle and globe or lantern are provided.

Figure 1 of the accompanying drawings illustrates in elevation anincandescent gasburner constructed according to this invention. Fig. 2is a plan thereof, and Fig. 3 is an elevation of a similar constructionwith the mantle-ring and mantle removed for the sake of clearness.

The burner illustrated in Figs. 1 and 2 consists of an atmosphericburner which is pref" erably bent or curved at or about the place markeda-that is. to say, between the head or mixing-chamber b and the point 0of the burner, which point delivers the mixture of gas and air to themantle. The burner is prolonged or formed with a tubular continuation,which is, as aforesaid, bent or curved at (601113 of the straight line,and preferably, as shown, that part of the tube near the point 0 of theburner is at a right angle to that part of the tube adjoining the heador mixing-chamber Z), which is, as usual, provided with holes (Z for theadmission of air, a nipple inside for the gas, and a sleeve e with holeswhich are adapted to register more or less with the holes into themixing-chamber, as is usual. By extending the burner and bending thetubular part of the same the burnerhead or mixingchamber 6 is removedfrom the path of the hot gases issuing from the mantle.

A suitable device for supporting a mantle in a convenient position at ornear the point 0 of the burner consists of a ring f, Figs. 1 and 2, towhich the mantle g is attached, which ring has (say three) internal lugs/L, Fig. 2, thereon, which pass up through (say three) slots 2' (seeFigs. 1, 2, and 3) in a ring in, which is fixed to the burner. The ring7': has upstanding sides Z with vertical projections, the spaces betweenwhich form shallow notches s, in which the lugs 71 rest when the ring fhas been turned round and allowed to drop into the said notches s; orother suitable means for supporting the mantle may be employed.

A suitable device for supporting a globe or shade consists of a ring onwith lugs not thereon, which clasp. the burner-tube and are held thereby a bolt or screw 0, or, as shown, by

two bolts 0 and 72 passing through the said lugs, while the ring isprovided with screws or the like for the attachment of the globe; or theringmay be attached to the burner by means of a bracket 0, as shown inFig. 3, which bracket is either screwed or riveted to the ring andscrewed to the burner.

What I claim as my invention, and desire to secure by Letters Patent, is

An inverted incandescent gas-burner comprising a horizontal limb, avertical limb at right angles to said horizontal limb, a mixingchamberon the free end of said horizontal limb provided with air-admissionports, a sleeve with registering ports mounted on said chamber, a burnerat the free end of the said vertical limb, a mantle-supporting ringfixed to the vertical limb an appreciable distance above the free endthereof. peripheral slots in said ring, segmental flanges on said ring,recesses in said flanges intermediate said slots, a mantle-ring adaptedto take over said supporting-ring, internal lugs on the mantle-ringadapted to pass through said slots and between said flanges and to seatin said recesses, and a globe-supporting ring mounted on the horizontallimb concentrically to the aforesaid rings and in a plane parallel withthe plane of said rings.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
